Young adults. Teen girls and young women usually need more calories than when they were younger, to support their growing and developing bodies. After about age 25, a woman’s resting metabolism (the number of calories her body needs to sustain itself at rest) goes down. To maintain a healthy weight after age 25, women need to gradually reduce their calories and increase their physical activity.
Omega-3s: These essential fatty acids, EPA and DHA, play many roles in the body, including building healthy brain and nerve cells. Some studies show that omega-3s, especially DHA, can help prevent preterm births. Even women who don't plan to have children should be sure to get plenty of omega-3s. These healthy oils have been shown to reduce the risk of heart disease, the number one killer of women.
The best training tool you're not using: a jump rope. “It may seem a little juvenile until you think of all the hot-bodied boxing pros who jump rope every single day,” says Landon LaRue, a CrossFit level-one trainer at Reebok CrossFit LAB in L.A. Not only is it inexpensive, portable, and easy to use almost anywhere, you’ll burn about 200 calories in 20 minutes and boost your cardiovascular health while toning, he adds.
CCTs have been more thoroughly evaluated for nutrition outcomes, particularly in Latin American countries. They were associated with improvements in women's knowledge of health and nutrition, as well as their self-esteem, participation in social networks, control over resources, and decision-making power (5, 202). Although intrahousehold allocation for women is not clear, CCTs increased household food expenditure and were associated with improved household dietary diversity, including increased household consumption of animal protein, fruits, and vegetables, and reduced consumption of staples and grains (14, 192, 202). There was also some evidence that household expenditure on fats and sweets also increased significantly (202). However, these findings were not consistent and some evaluations showed no significant increase (14, 202, 203). Despite this, in Mexico, there was evidence that in-kind and cash transfer programs resulted in excess weight gain in women who were not underweight (5, 93). This warrants future research given the burden of overweight and obesity among women.
The delivery of nutrition education reached women across all life stages and through many platforms. Many nutrition education studies that targeted pregnant and lactating mothers reported on women's outcomes, but the primary focus of many of these studies was child health outcomes (13, 14, 19, 21, 24, 28); few studies focused on dietary outcomes and behaviors of pregnant and lactating women themselves (17, 20, 23). There were some studies evaluating the impact of nutrition education on the practices and outcomes of school-age children and adolescent girls (15, 18, 27, 29, 34), as well as older women (16, 22, 25, 30). Many of the nutrition education interventions were clinic-based (17–20, 23, 24). However, nutrition education was also delivered through community-based programs, including home visits (16, 21), community centers (15, 16, 20, 21), worksites (25), and schools (25, 27, 30, 34).
